At the Center for Environmental Innovation in Roofing, we are deeply involved in integrating solar energy technologies into best roofing practice. In an effort to improve the coordination of roofing systems and PV solar installations, we have established an ongoing Rooftop PV Task Force that is developing useful guidelines for the mounting and anchorage of PV systems to both low-slope and steep-slope roofs. The first guideline covering PV racking and mounting criteria for membrane roof systems was published last year, and the second guideline covering metal roof systems is currently available for public comment.
Just as the Center has spent considerable time and resources to improve rooftop PV solar installations, we are also interested in other technologies that harness the power of the sun falling on our rooftops. These technologies include rooftop solar thermal, which offers an economical source of hot water for buildings, and roof daylighting, which can supplement a considerable amount of a building’s artificial lighting needs. When properly designed and installed, these technologies offer excellent return on investment for building owners as well as increased sales and profits for roofing contractors.
